Before installing the metal tube float flowmeter, be sure to clean up the welding slag and debris in the pipeline. In order to ensure the measurement accuracy of the metal tube float flowmeter, a straight pipe section of no less than 10DN should be added to the inlet end of the flowmeter, and a straight pipe section of no less than 5DN at the outlet end. The regulating control valve must be installed downstream of the flowmeter during measurement. .If the measured medium is a large pulsating flow or two-phase flow, a buffer should be installed upstream of the metal tube float flowmeter to eliminate or attenuate the pulsation and ensure that the flow of the medium is single-phase stable. At the same time, it is recommended that the flowmeter is best used Damping type. If the measured medium is dirty or contains magnetic particles, a filter or magnetic filter should be installed upstream of the metal tube float flowmeter. The installation of the metal tube float flowmeter should be able to properly support the vibration of the pipeline or reduce the axial load of the flowmeter, otherwise the support of the fixed flowmeter should be increased. In order to facilitate the maintenance and repair of the metal tube float flowmeter, the cleaning of the magnetic filter and the regular maintenance of the user pipeline, when the metal tube float flowmeter is used for gas measurement, it should be ensured that the working pressure in the pipeline is not less than 5 times the flow rate. The pressure loss of the meter enables the flow meter to operate stably and normally.Before using the electric remote transmission and the metal tube float flowmeter with alarm limit switch, open the meter cover, and wire it correctly according to the wiring diagram. For the alarm type of the screw at the limit switch, the user can set the limit alarm position as needed, tighten the screw, and use it after restoration.
